Blaine Sexton began playing ice hockey for the Windsor Swastikas in his native Nova Scotia. He joined the Canadian Army in 1916 and served as an officer in France during World War One where he was twice wounded. Sexton was also a capable fencer and during this period became sabre champion of the Canadian Army. After the war ended he returned to Canada but his British wife became homesick and he settled permanently in London from 1922 onwards and founded a successful tinned food business. A pioneer of ice hockey in Britain he founded the London Lions club in 1924 despite the lack of a suitable rink in the capital and took his team to play in Switzerland and Germany during the twenties and thirties. As a defenseman he was an important part of the national team for over a decade and played in the 1930 World Championships and 1926 European Championships as well as two Olympic Games. Sexton retired from playing at the age of forty in 1933.
